U.K. Prime Minister Keir Starmer will start a crucial week for his premiership by announcing a package of strong restrictions designed to protect British teenagers from online threats.

Starmer is expected Monday morning to confirm a ban on children under 16 using major social media platforms, as well as other measures including curfews on older teenagers and tough regulations on chatbots. He will then depart for a Group of Seven summit at Evian-les-Bains, France, where he faces awkward questions following last week¡¯s resignation of his defense secretary and uncertainty around the U.K.¡¯s military budget.

A ban on young teenagers using social media is popular with the U.K. public despite concerns around how effectively it can be enforced. The Labour government¡¯s new range of restrictions ¡ª including some against chatbots and online games ¡ª will go further than laws in Australia, according to a person familiar with the situation, where a ban on social media for teens came into effect last year.
